Summary
Built in 1978 by the USDA NRCS, this Earth-type dam stands at a height of 23 feet and spans a length of 1340 feet along the TR-Cow Creek. Its primary purpose is flood risk reduction, with a maximum storage capacity of 227 acre-feet and a normal storage of 22 acre-feet. The dam has a controlled spillway and one valve outlet gate for water management.
The dam's hazard potential is deemed significant, with a fair condition assessment as of the last inspection date in October 2011. The risk assessment for this site is classified as very high, indicating a need for vigilant monitoring and maintenance to ensure the safety and integrity of the structure. With state regulation and inspection in place, including enforcement by the OWRB, the SCS-Cow Creek Site-28 serves as a crucial infrastructure for managing water resources and protecting against potential flooding events in the region. Water resource and climate enthusiasts would find this site intriguing for its role in flood risk reduction and its significance in the local ecosystem.
Overall, SCS-Cow Creek Site-28 presents an essential component of water management infrastructure in Oklahoma, contributing to the mitigation of flood risks along the TR-Cow Creek. With its history of construction by the USDA NRCS and ongoing state oversight, this Earth-type dam plays a vital role in safeguarding the surrounding area from potential inundation. The site's location, design features, and storage capacity make it a focal point for water resource and climate enthusiasts interested in understanding the complexities of flood control and resilience in the face of changing environmental conditions.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
